Definition
High Minus Low (HML), a.k.a the value premium, is a key metric in the Fama-French three-factor model that quantifies the return spread between value stocks (high book-to-market ratios) and growth stocks (low book-to-market ratios). In simpler terms, HML captures the tendency of old-school, budget-friendly stock options to beat the high-flying, overhyped glamour stocks in a financial throwdown! ππ
HML vs. SMB
| Feature | High Minus Low (HML) | Small Minus Big (SMB) |
|---|---|---|
| Definition | Value premium derived from book-to-market ratio differences | Small-cap vs. large-cap performance |
| Focus | Compares value stocks and growth stocks | Compares small market cap stocks with large ones |
| Formula | HML = Return of value stocks - Return of growth stocks | SMB = Return of small stocks - Return of large stocks |
| Implications | Value stocks tend to outperform growth stocks over time | Small-cap stocks generally outperform large-cap stocks |
| Usage | Evaluating value investment strategies | Assessing performance in relation to market size |
Key Concepts and Formulas
The Fama-French three-factor model incorporates HML into its evaluation criteria of stock returns:
\[ \text{Expected Return} = R_f + \beta_m(R_m - R_f) + \beta_h \text{HML} + \beta_s \text{SMB} \]
Where:
- \(R_f\) = Risk-free rate
- \(R_m\) = Return of the market
- \( \beta_h \) = Sensitivity of the portfolio to value stocks
- \( \beta_s \) = Sensitivity of the portfolio to small stocks

- Book-to-Market Ratio: A financial ratio used to compare a company’s book value to its market value. A higher ratio indicates a value stock, while a lower ratio indicates a growth stock.
- Value Stocks: Stocks that trade for less than their intrinsic values, usually with a high book-to-market ratio. Think of them as the “unsung heroes” of stock investing! π
- Growth Stocks: Stocks that are expected to grow at an above-average rate compared to their industry or the overall market. These are your trendy, must-have stocks that everyone is buzzing about!
